Wireless sensor network, parameter optimization method thereof and warehouse system

A wireless sensor network, provided by the present invention, includes an aggregator, a control device, a bridge device, and a mesh module. The control device is connected with the aggregator and thebridge device, and the mesh module is wirelessly connected with at least one of the bridge device and the control device. A mesh network is built by the connections of the mesh module, the bridge device and the control device, and a duty cycle of the mesh module is less than or substantially equal to 10 percent. A command sent by the aggregator is converted into a wireless message by the control device, the wireless message is transmitted by the control device and is retransmitted by the bridge device with a first amount of radios, and the bridge device relays for a second amount of times, sothat the wireless message is successfully received by the mesh module, and the mesh network with high efficiency and low cost is achieved. 本公开提供一种无线传感器网络，包括聚合器、控制装置、桥接装置及网状模块。控制装置连通于聚合器及桥接装置。网状模块无线连通于桥接装置及控制装置中的至少一个。网状网络由网状模块、
